Inventory

This may be over the scope of your help, but maybe you can throw me a bone. I know the plugin (which is a great plugin) does not do inventory control. I can set a flag on the database to “closed” and will take the item off inventory which is fine with me as all the items are quantity of one.

Where in the php files can I insert an sql command to set the items flag to 1.
such as “update_post_meta($pid, ‘closed’,’1′);” every time a new item is added to the shopping cart and revert the flag to 0 when the item is taken off the cart.

Any help is appreciated it. 🙂
